Application October 24, 1956, Serial No. 618,021`

14 Claims. (ol. 222-79) My invention relates to toy pistols and is directed particularly to a water pistol or toy pistol operative to eject a stream of water or like liquid when the trigger is actuated.

Water pistols have heretofore been constructed in many different ways. Prior constructions, however, because of using check valves, closed pump cylinders, two-part molded water channels and pump cylinders, and other comparatively complicated and troublesome water-ejecting mechanisms, are diicult to assemble and relatively inexpensive to manufacture. l

lt is accordingly the principal object of my invention to provide an improved toy water pistol which utilizes a minimum of parts, which has no molded water channels, no two part molded pump cylinder, no check valves, and which does not require a closed pump cylinder.

lt is another object of my invention to provide a water pistol of the character described in which the body can readily be moldel in two parts of synthetic plastic material, the parting line being transverse to the longitudinal axis of the pistol barrel and extending substantially centrally through the pistol grip, thereby providing a complete unsplit, truer, open pump cylinder.

A still further object of this invention is to provide in a water pistol of the character described, a flexible tube extending from the muzzle to substantially the bottom of the pistol grip, thereby eliminating the necessity for a molded water channel, and permitting ejection of practically all of the water in the pistol.

Yet another object of this invention is to provide in a water pistol of the character described, a highly improved metal gun nozzle attached to the front end of a flexible tube and held in place by a disc at the front end of the muzzle of the gun. Y

Still another object of my invention is to provide a highly improved water pistol of the above nature, the parts of which are inexpensive to manufacture and easy to assemble, and which is compact, attractive in appearance, foolproof in operation, and durable in use.

Further objects, features and advantages of my invention will become apparent from the following description when read with reference to the drawings.

In the drawings, wherein like reference numerals denote corresponding parts in both views,

Fig. l is a longitudinal cross-sectional view of a water pistol embodying the invention;

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. l;

Fig. 3 is a cross-sectional View taken on line 3-3 of Fig. l;

Fig. 4 is a cross-,sectional view taken on line 44 of Fig. l;

Fig. 5 is a vertical cross-sectional View illustrating a modied construction of the muzzle of the gun; and

Fig. 6 is a view similar to Fig. 5 and illustrating another modification.

Referring now to the drawings, numeral 10 designates enerally a preferred embodiment of the improved water pistol comprising the invention. The water pistol 10 has its body formed of hollow front and rear shell members 12 and 14, respectively, which in assembled relation are cemented together at their open ends on. a parting line indicated by reference numeral 16. Thus the rear edge of the front portion 12 abuts and is adhered to the front edge of rear portion 14. The front shell member 12 is formed with a barrel portion 18 simulating the barrel of a` real pistol. The front and rear shell members 12 and 14 when in assembled relation form a downwardly extending grip portion 20 simulating the hand grip of a real pistol. The upper end of the rear shell member 14 is located back of barrel 18. Molded within the front shell member 12, below the barrel portion 18 thereof, is an open-ended pump cylinder 22 the front wall 23 of which comprises part of the front wall of shell 12 and is provided with an opening 24. Slidably disposed in the cylinder 22 is a cylindrical piston 26 of flexible material, preferably molded of polyethylene and formed with an outwardly and rearwardly extending outwardly flaring peripheral lip 28 which resiliently and wipingly engages about the interior surface of the pump cylinder 22. The piston 26 is formed at its forward end with a central circular rearward depression 30 within which is secured in any suitable manner, through the opening 24, the rearwardly-extending actuating arm 32 of a trigger member 34. The upper end of trigger member 34 is slidably disposed and guided for front to back motion in a channel 36 provided by a pair Vof spaced parallel guide rails 38 molded underneath the barrel portion 1S of the front shell member 12. i

A cylindrical boss 40 is molded within the rear shell member 14, said boss being so disposed as to lie in axial alignment with the pump cylinder 22 when the front and rear shell members 12 and 14 are in assembled relation. A compression coil spring 42 is constrained between and tted on the boss 40 and the annular seat dened in the rear end of the piston 26 by `the circular depression Sil thereof. The compression spring 42 is operative to normally hold the piston 26 against the end wall 23 of the piston cylinder 22 and thus urge the trigger 34 into its forwardmost position.

The muzzle end 43 of the barrel portion. 1S of the'front shell member 12 is formed or provided with an interior annular wall portion 44 having a rearwardly-extending central cylindrical opening 46 of reduced diameter cornmunicating with a forwardly-extending small diameter nozzle aperture 48. Fitted and sealed, in any suitable manner in the reduced diameter opening; 46 is one end of a iiexible length of tubing Si), preferably of a synthetic plastic material or rubber, the other end of said length of tubing being bent downwardly to extend almost to the bottom of the lower chamber within the grip portion 2l) of the pistol body. The lower end 51 of the tubing is angled so that opening 46 cannot close up by Contact with the lower end of the hand grip.

The upper end of the rear wall of the rear shell member 14 of the pistol body is provided withy a water charging opening 52 which can be tightly sealed by plug 6@ after charging the pistol with water W. l

ln operation, squeezing of the trigger 34 pushes the piston rearwardly in its cylinder 22 against the compressional force of the spring 42, reducing the total volume of the interior of the pistol and thereby forcing water W through the tubing 50 and ejecting it out `of the nozzle aperture 48 under pressure. Upon release of the trigger 34, the compression spring 42 will again move the pistol 25 against the front wall 23 of the cylinder, during which movement air will enter the pistol through the tube 5t) into the pistol interior to replace the volume of water ejected by the preceding actuation of the trigger.

In Fig. 5 there is shown a modied construction of the muzzle of the gun. AIn said figure, 'the muzzle 18a corresponding to lthe muzzle-18 of-Fig.- 1,y -has lfixed-in the front end thereof a disc 70 formed with a central opening 70a. Inserted into said opening 70a and fixed therein is ;a -metalmozzlefmember 7l. Saidfnozzle -member71 has a rearwardly tapering wall 72 and afront wall'753. The=frontfwall173 isv'formed Vwithl a central opening 75 and has an innerJ conical'-\wall'74. Thefinner'surfaceof wall 72 is cylindrical but' the VouterYsurfacethereof decreases towardstfthe rear. Inserted intothesocketformed by--member 71 and contacting the inner surface of the wall 72 is thefront'rend of tube Stiawhich is otherwise similar to tube 50 of -Fig. 1. vThe'tube 50a may-be adhered to Vthe/nozzle 71 in Vany* suitable manner and disc 70 may be cemented' or'otherwise adhered inA place-1in any suitable manner.

-In Fig. 6A thereis-shown another modilication, similar toFigs. l-and'S, except thatthefront end `43!) of the muzzle Altlrisj providedv with an; integrally molded transversefwall 7Gb. Saidrwall 70]; is formed with a central opening 70c,receiving a metal nozzle memberj71a. The latterhas -a wall 80 extendingthrough'the opening70c, afront wall-81 formed with a eentralpin opening'SZ, and a rear outwardly extending annular flange contacting wall lWbb. The front end of flexible tube 50a is fixed within the nozzle member 71a.

WhileI' have described a preferred embodiment of my invention, it is tobe understood that this disclosure is for the purpose of illustration only yand that various omissions, or changes in arrangement of parts, as Well as the'substitution of equivalent elements for those'herein shown and described may be made Without departing from the spirit and scope of the invention as set forth in the appended claims.
